| addition polymer | <chemistry> A polymer which is formed from the fusion of two monomers which join completely without losing any small molecules. (15 Jan 1998) |
|---|---|
| condensation polymer | <chemistry> The kind of polymer that is formed by the combination of monomers and the release of a small molecules at the point where monomers are joined. (05 Jan 1998) |
| polymer | <chemistry> A macromolecule made of repeating (monomer) units or protomers. (18 Nov 1997) |
| polymer fume fever | An occupational disease marked by fever, pain in the chest, and cough caused by the inhalation of fumes given off by a plastic, polytetrafluorethylene, when heated. (05 Mar 2000) |
| alu sequence | Any of a family of short (300 basepairs long) repeated sequences that occur throughout the human genome. (09 Oct 1997) |
| amino acid sequence | The sequence of amino acids as arrayed in chains, sheets, etc., within the protein molecule. This is referred to as the primary structure of proteins. It is of fundamental importance in determining protein conformation. (12 Dec 1998) |
| autonomously replicating sequence | <molecular biology> This is a chromosomal sequence that allows plasmids to replicate on their own in yeast. (02 Jan 1998) |
| base sequence | <molecular biology> The order of nucleotide bases in a DNA molecule. (09 Oct 1997) |
| base sequence analysis | <molecular biology> A method, sometimes automated, for determining the base sequence. (09 Oct 1997) |
| canonical sequence | Of a series of related DNA, RNA or protein sequences, the sequence that reflects the most common choice of base or amino acid at each position. Areas of particularly good agreement often represent conserved functional domains. The generation of consensus sequences has been subjected to intensive mathematical analysis. (18 Nov 1997) |
| carbohydrate sequence | The sequence of carbohydrates within polysaccharides, glycoproteins, and glycolipids. (12 Dec 1998) |
| palindromic sequence | <molecular biology> Nucleic acid sequence that is identical to its complementary strand when each is read in the correct direction (e.g. TGGCCA). Palindromic sequences are often the recognition sites for restriction enzymes. Degenerate palindromes with internal mismatching can lead to loops or hairpins being formed (as in tRNA). (18 Nov 1997) |
| recognition sequence | A nucleotide sequence --typically composed of 4, 6, or 8nucleotides -- that is recognised by a restriction endonuclease. Type II enzymes cut (and theircorresponding modification enzymes methylate) within or very near the recognition sequence. (09 Oct 1997) |
| regulatory sequence | <molecular biology> DNA sequence to which regulatory molecules such as promotors or enhancers bind, thereby altering the expression of the adjacent gene. (18 Nov 1997) |
| centromeric sequence | <molecular biology> Special sequences of DNA nucleotides found on chromosomes which provide a site for the attachment of spindle fibres during nuclear division (mitosis or meiosis). (09 Oct 1997) |
